Troubleshooting Faults and Warnings
How to Check the Warning and
Fault Queues
When a fault condition occurs, the RGU will store the fault information in
the fault queue. The fault queue will indicate the fault condition, the
sequence number of the fault, and will display ‘Trip’ if the fault caused the
RGU to trip. To view the warning or fault queue with a HIM, choose
Control Status, then choose either Fault Queue or Warning Queue, then
choose View Queue to open the queue (as shown in Figure 3.3).
Figure 3.3
Checking the Fault Queue–HIM
Typically, the fault (or fault queue) will need to be cleared before the RGU
can be enabled again. To clear the fault queue, choose Control Status, then
choose Fault Queue, then choose Clear Queue (as shown in Figure 3.4).
The fault queue will clear, and the unit can be enabled again (a reset may be
required to rectify any hardware or software conditions).
